How would one lock past events now? In the old system one could simple disable the date field in Edit mode. In the new system the Drag & Drop feature only calls the date field On Update script, so what On Update script would one use to cancel such an attempt to change a past event using the Drag & Drop feature?
UPDATE: To prevent the Drag & Drop from changing dates I put a script at On Update for the Date field which basically changes it back right away to what it was and then refreshes the page...BUT I can't trigger an alert in On Update, so all I could do is add a notice to my html that the Drag & Drop has been disabled and only results in a page refresh....sad.
Does anyone know of a better way to Disable Drag & Drop?
I really think the Drag & Drop feature should call On Edit as a default and then have a setting which enables it to not make that call. This would assure developers the ability to control date changes.
